Hypercalciuria is a relevant complication in patients with treated hypoparathyroidism. While hypercalciuria is usually estimated by 24-hour urinary calcium excretion (24hUCa), the calcium/creatinine ratio (CaCrR) of a morning urine sample is more often used in pediatric endocrinology due to feasibility. This study aims to compare these two approaches in adult patients with hypoparathyroidism.
